similar to: Combining simulated data

Hi   Out of curiosity, how can i determine the minimum required sample size of this data in a combined form say 100 entries which r functions can i use?   R helpers   Please help me combine the simulated data to a form of table where: Hypermarket have 10 rows, supermarket have 15 rows,......., spazashops with 35 rows.   Hypermarket <- rnorm(10, mean=20000, sd=7000) Supermarket <-

Dear Helpers   I have a sample frame and i have sampled from it using three methods and now i want to calculate the statistics but i only get the population parameters.   H <- matrix(rnorm(100, mean=50000, sd=5000)) sampleframe=data.frame(type=c(rep("H",100)),value=c(H)) sampleframe   str=strata(sampleframe,c("type"),size=c(20,), method="srswor")

R-helpers   A curious question: Can you make suggestions  as to  what to use in R for the data from a sample of the following:   Hypermarket <- matrix(rnorm(100, mean=50000, sd=5000)) Supermarket <- matrix(rnorm(400, mean=34000, sd=3000)) Minimarket  <- matrix(rnorm(1000, mean=10000,sd=2000)) Cornershop  <- matrix(rnorm(1500, mean=2500, sd=500)) Spazashop   <- matrix(rnorm(2000,

R -helpers   i have been trying to do this problem without must success,i managed to do a graph for x, but it is not what i want to define,(i want to specify number of observations as well). I have also been able to do simple rendom sample.   data.frame(ID=c(1,2,3),mu=c(10000,34000,50000),sigma=c(2000,3000,5000)) curve(dnorm(x,mean=parms$mu[1],sd=parms$sigma[1]),from=2000, to=80000,

I am using Console/DSP for an intercom. I want to play my MP3 collection over it when no one is using it, like when they do in the supermarket. Can anyone help me with this. Any suggestions will be appreciated. -- Christopher Dobbs

Hi, Problem Summary: I have been trying to add the highlight effect to my table but everytime a new record is added the highlighting gives an rjs error. However when i click the add to cart button on a product that already exists inside the table, the highlight effect works. Is this because the partial must only have only one <tr></tr> in it and the <table> must be on the other

Hi, I want to have a page in my Ruby on Rails application that is like a dynamic / updateable data grid. Like a matrix or spreadsheet segment (x rows, y columns) which one can click in any of the cells and make an update, which triggers some AJAX code to fire off the update, and then the responses come back and update whatever else needs updating based on this change. Is there a prototype

R-list   I am sorry for asking this stupid question, but i have been running in circles. I want to randomly generate a scaling point of between 1 and 10, for say hundred entries, where the first 10% percent is has rates between 2 and 7, the next 15% 3 and 7, 20% between 3 and 9, 20% between 3 and  10, 35% between 5 and 10. The problem is that i can only generate the usual 100 using runif function

In a OpenOffice.org forum someone was asking if the spreadsheet could graph this http://www.elmundo.es/elmundosalud/documentos/2011/06/leche.html I didn't think it could. :) I don't think I've ever seen exactly this layout. Does anyone know if there is anything in R that does a graph like this or that can be adapted to do it. Unfortunately my Spanish is non-existent so I am not

Dear All ? I know that you do not have to help me but please do, i am new to R as a CPI compiler, i just need to do a sample to see which sampling method best works in different situations, therefore since this is for practice purposes nobody will finance a real project thats why i need you to help me direct me as to how simulate data (just direct me,not 100% help). See my attachment for problem

I just downloaded & installed the final release and it works fine for me. There is still the old problem with Winamp crashing when a vorbis stream is interrupted or the internet connection is dodgy. This is an issue with in_vorbis.dll v1.35 and Nullsoft don't appear to want to fix it. I'm having to recommend my clients to use MP3 for streaming to supermarkets, malls etc because of

Dear All   I hope you can help me with this small problem. I want to draw a normal distribution line to this data: p<-rnorm(100, mean=50000, sd=3000) hist(p)   Kabeli [[alternative HTML version deleted]]

 Dear All   let me go one step further by asking you if you could help me show that the distribution of this data in normal.  have a little idea (by trial and error) but i seem to not fully understand how its done.   H<-rnorm(100, mean=50000, sd=3000) par(las=1) hist(H, breaks=seq(40000, 60000, 1000), freq=F) f<- function(x) exp(-(x-5000)^2/18000000)/sqrt(18000000*pi)  x<- seq(40000,

Could someone recommend 5 different varieties of red wine, average price available in a supermarket for a novice to get a good overview of what's out there? :P

I just tried to install an ancient detective-type RPG ( I am not up with the classifications.) (a) It offered to install DirectX. Since Wine has its own DirectX, I ignored that. (b) The game failed to run because (according to the message box) it couldn't find DirectDraw. This showed as a Fixme in the terminal, while the error message was to do with the display settings - there was no mode

Hi, I have some trouble with the following: I have a table of 7 rows and 6columns. The columns 1,2,3 have information about the number of employees. The columns 4,5,6 have information about the number of working hours. Each row, is corresponding with a week. My goal is to make a boxplot, histogram etc. of the columns 4, 5 and 6 (thus, the data of the number of working hours). How can I select by
